' 'ADJUSTABLE Application tiled November To all uiom. il may concern.'

' Be itknown that I, l"i'..\.\cislEi.i.swoiiTii Bi'x'iox, a citizen of the I'nited States, resid' inir in the city of lticliii'ioiid, iii the county of F u lWayne and State of Indiana, have invented certain new and useful Improvements in A.dj iistable Journal-Boxes, in addition to that secured to me bv Letters Patent of the lnited States on the th dav of June, 1907, .\`o. $57,758, and referred to hy same title as ahove.

'lhe following is a full and accurate .specilieatioii of mv present invention, being siieh as will enahle others to mal-.emol use the same with absolute exactitude.

'lhe ohjeet o` in v present invention is to provide an adjustablejournal-box or bearing which will he strong and durable in construction. neat and attractive in appearance,

i which will he simple in its several parts and eas-v io :ii-tante, and which can he manufactured and solcl at a. comparatively low price.

ore specifi-'ally stated in v ohjeet is to provide a journal box by which I an enabled to compensate for the wear on aeeoiiiit of the rotation ofthe shaft operative therethrough, whereby the shaft mav be retained suhstantially true with relation to the parts with which it is connected.

Further particular objects are to provide a journal box incorporating in its construction a plurality of segmental hearing elements, having sleeves for their adjustment, with means wliereliv I ain enabled to rotate the sleeves independent of the.adjustment., and to provide forjjthe adjustment of the `sleeves longitudinally independent of the rotation.

.\ further object is to provide means, iii

eonneetion with a journal box, for the-more accurate.adjustment of the surrounding hearing parts or segments, independent. of

each other in Yregard to their side margins; they heiiig iin-lose in sleeves, which are adjustahleiioiigi.iidmallv, the operation of the two sleeves heilig oppositel) disposed with relation to each other in their longitudinal movements.

Another object is to provide a journal-box or the like having a continuous bearing snrface 'from end to end and surrounding the shaft. heilig sup iorted, with ineans for avoith loose wedges, set-screws, and

Similar reference characters denote like parts throughout the .several viens of the drawings.

In order that the construction and operation of the invention may be more fully understood I will now take up the description thereof in which l `will describe the several parts and their relation one to the other as riefly and as compnetly as I mesi In the drawinas the let-ter A designates `the fixed portion ormse member of the boxing, and the indice A' denotes the removable cap therefor, the lat-ter being' securable te the Formed centrally and horizontally through the base and cap is a shaft aperture which is of greater diameter than is. the shaf t to be carried, the

, s ace formed by said aperture beinr equally wided in the base A and the cop A as ind1- looted. Formed through the center of the f eap A', atright :ingles to said horizontal apex-ture, is an' oblong aperture which ex# tends down and then opens con rergently into said horizontal aperture, with its sides forming angles which are at right .angles to said shaft e erture.

L,The otter M designates n key plug corresponding in lgeneral outline to said vertical aperture in t e cap, see Figs. l and 9..

The indexes B and B designate two sleeves which are identical with each other but are oppositely disposed, euch having a portion of its periphery threaded on its inner end portion .iith right und left threads, respectively, as indicated. Connecting said sleeves is a bond G provided with interior and left threads to engage the thrends o the res ective sleeves, as shown in Fig. 5, by whic i if the band G be rotated in one direction the sleeves will be d rnwn towards each other, and if rotated in the other direction. the sleeves will be forced a art.

In the inner ace of the sleeves B and B I form two angular grooves or channels, E and E', respectively, es indicated, with their longitudinal angular inclination such as to give the proper movement to the segmental beerings presently referred to, said grooves E and E being provided with parallel margins and s need substantially opposite each other.

either side of said grooves Ff-E are formed two respective lint surfaces F and F shown in Figs. It) and 15, and they extend parallel through the sleeves Band B' asindicated. These angles E-E and surfaces F-F are formed in the. outer end portions of WQ p, 895,425

and be free to more in said aperture.

and surround- H'ithin the sleeves B and l ing the sha-"t S are arranged vt wo benring segments l) und D', which are identical with each other, find they are spared a proper dis tance a mrt to allow for tultinv up the weer caused y the rotation of the snaft S. Each of the segments l) D' has an outwardly extending proeetion or rib, Dl anl D, extendin;r lon fitut inally thereof nnd located op o# site eacih other and whose sides are par lel with each other. The projections D' and D are formed smaller et their extremities in order thnt the sleeves B and B may be re moved without displacing the lsegments D and D'. Said projections D and D are adapta-d to operate ioiwitudinally in the res eeti've. grooves E an E,`as indicated in i igs. 6 and 1t). Intermediate the ends ofthe. segments D and D is formed a series of apcr'- tures d to rovide means for engaging a. wrench J or t ie like to rotate the segments as desired.

Formed around in the periphery of theband G are a number of equidistnntcavities 3', in which may be engaged the Wrench J' for rotating the band (lr. Formed throuvh the band G ere a plurality of apertures 4, laocated alternately between said cavities, throueh which may pass the. prongs of the wrene J in order to engage the notches d of the segments D and 1)', as shown in Fig. 6. The wrenches J and J may in fact be united b v a body or handle common to both, thereby forming,r one tool.

By turning the ring G a positive' adj-ast ment towards a center of axis may be provided on the segments D-D'. The sleeves B-B' are of course free to move longitudinelly as the band@ is rotated. By turning the. band G with the wrench J- it 1s evident that an equalizing opening and closing ad- 'ustment is obtained b v the segments moving towards or from each other, and a longitudinal adjustment is obtained by the sleeves moving in an exial direction towards or from each other.

rhe open ends of the boxin are cled by the caps I and i. The cap ieeeured by the screws 2, and the cap I is secured by the screws 3. The caps I and I' should be cast in a manner to be broken into two equal @der tions as is indicated. z

In the shaft opening are formed oblong. grooves 12 to receive two semicircular 0r crescent-shaped OiLrings 13 and 14 whieh connect on o ;posite sides of the shaft. Sarl Yrings are hel from turning by their exterior sov los

for."` and are retained in engagement with the shaft S bythe sprinosjl and t6, as indil cated in Fig. '4. The onction of said oill rings being to reduce to a minimum the es- -cape. of oii from the journatbox.

Ihe key .\Iwill, norniaily, be retained in position by gravity, being seated neatly in the aperture formed therefor, but it may bc secured if desired by a cap and nut, substan- 1-0 tiall'y as indicated in Figs. 1 and 2.

` By the above description of the eoostructien it will he notably ap iarent that I pro; vide means whereby the shaft and the rotative parts ofthe boxing may be, at least. -i.artially submerged in oil, which may be injected into the boxing through the key aperture in the top of the cap A'.

It will be apparentfrom the above description that in rotating the sleeves BB, in'

means of the band G actuated b v the wrench J, that it will also turn the bearingsegments t 'DD\about the shaft S so that the position of. 1e usuai hearing surface will be changed with relation to the shaft. It will also be ob- -viens that. a horizontal movement of the sleeves B-B, actuated by the uwrench J operating on tlie band G, wiil force the segragots against. the shaft S, or will relieve the c'lose adjustment, of the segments allowing theln th' open out, according to the direction of the rotation of the band G.

In practice the base A is first placed in position, the can A being removed, and the shaft S suspended in the approximate position therefor. The sleeves B and B are suspeided loosely around the shaft on each side of the box, with the band (i surrounding the shaft and hanging loosely within the boxing. CI now bring the tw'o bearing seg- 40- ments, D and'D, to osition aroundthe shaftand within the casing, thc band (i having been previously encircling -the segments and located centrally thereof, 'I then enter the threaded ends of the sleeves in the band',

the threads being started by rotating the band. In this last position I have. of course caused Jthe said projections of the segments to entr the grooves formed on the inside of the sleeves. Nm.' by rotating the band G 5D thc steeves ma) be drawn towards each other which will cause the segments to be foreed towards cach other adjustiiny them at the desired pressure against the `soaft After "said adjustment is obtained I then position the cap A and secure it to the base by the bolts` u, as shown. The adjustment of the bearing- .Qgments in relation to the shaft having 'neen previously obtained I now insert the key `.\I in the aperture therefor in the eap A'. allowing the prongs of said key to pass through the eornsi o|uli1ig apertures 4 in the band with their points entering corresponding notches d in the .segments D-D, as shown. B the above it. is ap- .;.5 parent that the. key 1N is caused. to lock the said parts together in their adjusted position. thereby forming the parts into a fixed unit. v

In the event of the interior of the segments becoming worn, and the shaft having lostA 'i itsl center of axis within the boxing, l propose to conmcnsate therefor as follows: I first remove thc ke .\l, and in place thereof insert the wrench .l and then rotate together the segments l)- lV. the band (Land the sleeves B- di'. bri: ing the woln port? n of the segments to a new position. .\ftcr the above l remove tbc wrench -l and insert the wrench J' to engage the band (i as in Fig. R, and then rotate the` hand (i to draw the sleeves iis-' towards each other until the segments l)--l) are again in propel' engagement with the shaft. l now remove the wrench J and insert the key .\l, as before. By these operations I attain a new adjustment. and,- if desired, a new hearing surface, thereby compensating for the previous wear, therein' attaining the particular objects of my invention.

ln Figs. l, 2, {i} and l-f l have shown a modified form of construction, in which I have shown four segmental bearirgs in place of two, each segmentbcing provided with means for its maintcname in position and for its guidance b v the operation of the' band .inside the sleeves are arranged the quarter bearings K, K, K" and K, as

shown in. Fig. t, same is provided with suit-4 able clearance s race therein-tween which may be filled wit i a suitable substance for filtering aud retaining the oil in suspension. Said quarter bearings are cut away and beveled adjacent. their sides by lines located at substantially forty-five degrees inclination. Said quarter bearings arc formed with reverse angles at their cxtreme ends to connect n'ecisely wh companion projections in t le sleeves. Said sleeve projections are formed higher at their extreme ends 'toallow their removal. ln rotating the ring (i in one diredtion said quarter bearings all move. centerward on parallel ways, or the reverse to open out. In other respects the modifications are. substantially the same as the preferred construction. lbe operation of both forms is substantially the same, the

modified form being designed mainly for extra heay dut While Iiiave herein shown and described the best means to me known at this time for the construction and operation of my invention, l desire that it be undelstoodthat various changes may be made in the details of construction thereofI without departing .from the spirit of the invention oi: sacrificing anv of thc advantages thereof.
